degradation of acrylic water base color from synthetic wastewater by the fenton process was performed. experiments were conducted on the sample containing 100 and 400 mg/l of acrylic water base color. the study was performed for searching optimum values of feso4 and h2o2 concentration, ph and temperature. the h2o2 requirement seems to be related to initial cod of the sample. feso4/ h2o2 ratios ...

PURPOSE The aim of this study was to compare the color stability, water sorption and cytotoxicity of thermoplastic acrylic resin for the non-metal clasp dentures to those of thermoplastic polyamide and conventional heat-polymerized denture base resins. MATERIALS AND METHODS Three types of denture base resin, which are conventional heat-polymerized acrylic resin (Paladent 20), thermoplastic po...

conclusions coffee caused the most color changes in the examined resin denture teeth. tea and cola left less staining on the teeth, and distilled water caused the least discoloration. generally, investing by heat- and cold-cured acrylic resins can significantly affect the color stability of resin denture teeth; however, heat-cured acrylic resins had fewer color changes. results there were signi...

BACKGROUND Use of alkaline peroxide denture cleanser with different temperature of water could cause a change in surface hardness of the acrylic denture and also has a bleaching effect. The purpose of the study was to determine the effect of increased water content during thermal cycling of hot water-treated acrylic on the surface hardness of acrylic denture base when compared to warm water tre...

PURPOSE The discoloration of acrylic resin denture bases may lead to significant esthetic problems. The aim of this in vitro study was to investigate the effects of frequently consumed drinks on the color changes of fresh and aged, heat-polymerized, conventional acrylic resin. MATERIALS AND METHODS Eighty-four, heat-polymerized acrylic resin specimens (4 mm x 5 mm x 30 mm) were fabricated. Ha...
